CROSS-REFERENCE TO RELATED APPLICATIONS

This patent application claims priority as a continuation fromco-pending U.S. non-provisional patent application Ser. No. 17/491,053,filed 30 Sep. 2021, entitled “WHEELBARROW AND KIT FOR ASSEMBLING SAME”,having a common applicant herewith and being incorporated herein in itsentirety by reference.

FIELD OF THE DISCLOSURE

The disclosures made herein relate generally to wheeled materialtransport structures and, more particularly, to multi-componentwheelbarrows configured to be assembled in a manner that provides forstructural rigidity.

BACKGROUND

Wheelbarrows are well known to be useful for manually carrying heavyloads. Wheelbarrows are often used to move loads across uneven ground,un-level and/or soft surfaces. They generally include a tub (i.e., atray or bin), at least one wheel, a frame having a pair of legs and apair of handles attached thereto. These components are often discreteitems that are interconnected via mechanical fasteners (e.g., screws,bolts, nuts, washers and the like). These components being in the formof discrete items is beneficial from the standpoints of manufacturing,shipping, warehousing and the like.

A wheelbarrow is moved by lifting its handles to raise the legs off theground, balancing the wheelbarrow on its wheel(s), and then walkingwhile pushing or pulling the handles in a desired direction. A keyattribute of wheelbarrows is their ability to easily dump a load beingcarried within the tub. A wheelbarrow is typically unloaded by liftingthe handles to tip the tub into a vertical position where the loadslides out a sloped front end portion of the tub. Often, in order todump the load out of the tub completely, a wheelbarrow user is requiredto shake and rock the wheelbarrow back and forth and to sometimes tiltthe tub over beyond the vertical position.

As the weight of the load being carried by a wheelbarrow increases, itoften becomes more difficult to carry the load, to balance thewheelbarrow while moving the load and to dump the load. The increasedweight of the load results in increased forces being exerted on thestructure of the wheelbarrow during all aspects of use thereof. Mostnotably, the tub, legs, handles and interconnections between exhibitexertion of such increased forces thereon. Oftentimes, forces exerted onthese components of the wheelbarrow and interconnections thereof (evenwith loads within general specifications and intended use of awheelbarrow) result in the interconnection between the aforementionedcomponents exhibiting diminished structural integrity. A common problemfurther diminishing the ability to keep components fastened withstructural integrity is the loosening of fasteners during transport of awheelbarrow between jobs carried on naturally vibrating trucks. Hence,there is a general objective to be less reliant on fasteners forstructural integrity and to reduce the variability of joint integritydue to assembly mistakes. As a result, these components tend to deflectand/or displace relative to each other and thereby further compromisethe structural integrity of the interconnections and, in the process,adversely impacting operability of the wheelbarrow—e.g., more difficultto balance the wheelbarrow, requiring more effort to move thewheelbarrow, more effort to dump the wheelbarrow and the bending orfracturing of parts.

Therefore, a wheelbarrow (or other similar types of wheeled materialtransport structures) that comprises a plurality of interconnecteddiscrete structural components and that overcomes or substantiallymitigates the aforementioned structural rigidity drawbacks associatedwith conventional wheelbarrows would be beneficial, desirable anduseful.

DETAILED DESCRIPTION

Referring now to FIGS. 1-5 , aspects of a wheelbarrow configured inaccordance with one or more embodiments of the disclosures made herein(i.e., wheelbarrow 100) are discussed. The wheelbarrow 100 comprises aplurality of interconnected discrete structural components implementedin a manner that enhances and maintains structural rigidity at theinterconnections between such components. As discussed below in detail,such interconnection arrangement advantageously improves operability andlongevity of use of the wheelbarrow 100 and other similar types ofwheeled material transport structures that utilize such animplementation of the interconnected discrete structural components.Such an interconnection arrangement enhances the utility and value ofthe wheelbarrow 100 and other similar types of wheeled materialtransport structures that are intended to be shipped in an unassembledformat.

The wheelbarrow comprises a frame 102, a wheel 104, a tub 106, supportlegs 108, a leg brace 110 and handles 112. The wheel 104 is attached toand located below a forward portion of the frame 102 in a mannerenabling the wheel 104 to be freely rotated about a rotational axis Rextending through a central axis of the wheel 104. The tub 104 isattached to the frame 102 and extends above an upper surface of theframe 102. The handles 112 are attached to and extend rearwardly from arear portion of the frame 102. The support legs 108 are each engagedwith the frame 102 and extend below a lower surface of the frame 102.The leg brace 110 is engaged with the frame 102 and with each one of thesupport legs 108. As discussed below in detail, the handles 112 are eachattached to the frame 102 in a manner that enhances and maintainsstructural rigidity at the interconnections therebetween and the legbrace 110 is engaged with the frame 102 and with each one of the supportlegs 108 in a manner that enhances and maintains structural rigidity atthe interconnections therebetween and associated therewith.

It is well known that wheelbarrows may include one or more componentsthat are used in pairs. For example, as shown in FIGS. 1, 3 and 7 , thewheelbarrow 100 includes a pair of leg supports (i.e., the leg supports108) and a pair of handles 112 (i.e., the handles 112). A person ofordinary skill in the art will be well aware that such components usedin pairs may be identical to each other (e.g., as handles often are) ormay different than each other (e.g., minor images of each other assupport legs often are). In regard to the disclosures made herein, use asingle reference number to designate components used in a paired manner(e.g., spaced-apart) does not necessarily imply that such components areidentical to each other.

Each of the handles 112 has a frame engaging body 114 at an end portionthereof. The frame 102 has spaced-apart handle engaging bodies 116 at arear portion thereof. The frame engaging body 114 of each handle 112 isengaged with a respective one of the handle mounting bodies 116 tojointly define a respective handle coupling 118. Each handle coupling118 comprises a first tubular member 120, a second tubular member 122and a third tubular member 124. The second and third tubular members122, 124 are integral with a respective one of the handles 112. Forexample, as shown, the second and third tubular members 122, 124 of eachhandle 112 are fixedly attached to an elongated body 125 of a respectiveone of the handles 112. In preferred embodiments, the second tubularmember 122, the third tubular member 124 and the elongated body 125 ofeach handle 112 are fixedly attached to each other such as by welding.For example, the second and third tubular members 122, 124 can each bewelded to the elongated body 125.

The second tubular member 122 is engaged within a central passage of thefirst tubular member 124 and the first tubular member 120 is engagedwithin a central passage of the third tubular member 124. The secondtubular member 122 is preferably matingly engaged within the centralpassage of the first tubular member 124 and the first tubular member 120is preferably matingly engaged within the central passage of the thirdtubular member 124. Such tubular members being matingly engaged withinthe respective central passage includes the second tubular member 122having a close-tolerance slip-fit within the central passage of thefirst tubular member 120 and the first tubular member 120 has aclose-tolerance slip-fit within the central passage of the third tubularmember 124. In the context of the handle couplings 118, aclose-tolerance fit involves inside dimension(s) of a tubular member andoutside dimension(s) of an engaged tubular member enabling manualengagement of the two tubular members without the use of tools whileinhibiting appreciable play between the two tubular members. Forexample, a clearance of a few thousands of an inch to a few hundreds ofan inch will generally provide a suitable close-tolerance slip-fit asrelated to wheelbarrows and other similar types of wheeled materialtransport structures.

The second tubular member 122 extends from within the central passage ofthe third tubular member 124 into the central passage of the firsttubular member 120. In one or more embodiments, as shown in FIGS. 2-4 ,the first tubular member 120 has one or more fastener holes 126extending therethrough and the second tubular member 122 has one or morefastener holes 128 extending therethrough. As best shown in FIGS. 1 and5 , when the frame engaging body 114 of a handle 112 is fully engagedwith the respective one of the handle engaging bodies 116, each of theone or more fastener holes 128 of the first tubular member 120 isaligned with a respective one of the one or more fastener holes 128 ofthe second tubular member 122. A fastener 130 may be engaged througheach of the aligned fastener holes 126, 128 for fixedly securing thehandle 112 to the frame 102.

In one or more embodiments, as shown, all of the tubular members 120,122, 124 have the same cross-sectional shape—i.e., round. However, inone or more other embodiments, one or more of the tubular members 120,122, 124 may have a cross-sectional shape different that round (e.g.,square). The first tubular member 120 may be a solid rod or the like andstill be a tubular member as relevant to the scope of the disclosuresmade herein.

In view of the disclosures made herein, a skilled person will appreciatethat the structural arrangement of the handle coupling 118 may be usedin other applications beside that of a wheelbarrow and other similartypes of wheeled material transport structures. The structuralarrangement of the handle coupling 118 provides exceptional rigiditybetween to interconnected bodies and, particularly, elongated members.Examples of such other application include, but are not limited to,tools (e.g., long-handled gardening tools, extension poles, etc.),support bodies for support structures (e.g., table legs, awning legs,etc.), building materials (e.g., fence posts, etc.) and the like.

The support legs 108 preferably have spaced-apart end portions 108A,108B. A first end portion 108A of each support leg 108 is attached tothe frame 102 at the rear portion of the frame 102 and a second endportion 108B of each support leg 108 is attached to the frame 102 at aposition forward of the attachment location of the first end portion108A. For example, as shown, the second end portion 108B of each supportleg 108 may be attached to the frame 102 at a central portionthereof—i.e., a location between the front and rear portions of theframe 102. Placement, construction and shape of support legs forwheelbarrows and other similar types of wheeled material transportstructures are well- known in the art. Accordingly, in view of thedisclosures herein, a skilled person will appreciate further details asto placement, construction and shape of the support legs of wheelbarrows configured in accordance with embodiments of the disclosuresmade herein.

The leg brace 110 is coupled to the frame 102 and to each of the supportlegs 108. In preferred embodiments, the leg brace 110 constrainsmovement of the support legs 108 relative to each other and relative tothe frame 102. Advantageously, in a preferred embodiment as shown inFIG. 3 , the leg brace 110 constrains movement of the support legs inmultiple rotational and linear translational directions—i.e., fore andaft movement, lateral movement and 3-axis (orthogonal) rotationalmovement of each of the support legs 108 relative to the leg brace 110.Such constrained movement advantageously enhances and maintainsstructural rigidity at interconnections between the frame 102 and thesupport legs 108 to thereby improve operability and longevity of use ofthe wheelbarrow 100 (i.e., a wheel barrow configured in accordance withone or more embodiments of the disclosures made herein).

As shown in FIG. 3 , in a preferred embodiment, the leg brace 110 (e.g.,a tubular body) includes an upper portion 110A and a lower portion 110B.The upper portion 110A of the leg brace 110A is positioned within alaterally-extending channel 102A of the frame 102. The upper portion110A of the leg brace 110 and the channel 102A are jointly dimensioned(e.g., via a close-tolerance slip-fit of the upper portion 110 withinthe channel 102A) for constraining fore and aft movement of the upperportion 110A of the leg brace 110 relative to the frame 102. The upperportion 110A of the leg brace 110 may have a close-tolerance fit withthe channel 102A of the frame. In the context of the leg brace 110, aclose-tolerance fit involves a width of the upper portion 110A of theleg brace 110 and a width of the channel 102A of the frame 102 enablingmanual engagement of the upper portion 110A of the leg brace 110 withinthe channel 102A of the frame 102 without the use of tools whileinhibiting appreciable play therebetween. Preferably, all portions ofthe leg brace 110 may be welded together.

In view of the disclosures made herein, a skilled person will appreciatethat other interconnect structures may be used between the upper portion110A of the leg brace 110 and the frame 102. Such other interconnectstructures would provide the desired functionality of inhibitingunrestricted fore and aft (and optionally lateral) movement between theupper portion 110A of the leg brace 110 and the frame 102. For example,in other embodiments, a stub and receptacle structure or the like (asdiscussed below in reference to the lower portion 110B of the leg brace110) may be utilized as an engagement means between the upper portion110A of the leg brace 110 and the frame 102.

The lower portion 110B of the leg brace 110 is engaged with each of thesupport legs 108 for constraining fore and aft movement, lateralmovement and rotational movement of each of the support legs 108relative to the lower portion 110B of the leg brace 110. The lowerportion 110B of the leg brace 110 includes protruding stubs 132 eachengaged within a passage 134 of a stub receptacle 136 of a respectiveone of the support legs 110. Each protruding stub 132 and the passage ofeach stub receptacle 134 has a rectangular cross-sectional shape. In oneor more other embodiments, each protruding stub 132 and the passage ofeach stub receptacle 134 may have a different cross-sectionalshape—e.g., round. The protruding stubs 132 and passage 134 of each stubreceptacle 136 are jointly dimensioned (e.g., via a close-toleranceslip-fit of the protruding stub 132 within the passage 134 of the stubreceptacle 136) for constraining fore and aft movement, lateral movementand 3-axis (orthogonal) rotational movement of each of the support legs108 relative to the leg brace 110.

Referring to FIG. 3 , the leg brace 110 includes a cross-member 111. Asshown, the upper portion 110A of the leg brace 110 includes a curvedtubular member having opposing end portions thereof attached to thecross-member 111. As also shown, the protruding stubs 132 of the lowerportion 110B of the leg brace 110 are each attached in a spaced-apartmanner to the cross-member 111. It is disclosed herein that, in one ormore embodiments, a central portion of the cross-member 111 may beomitted—e.g., all or a portion of the cross-member extending between theopposing end portions of the upper portion 110A of the leg brace 110. Itis also disclosed herein that, in one or more other embodiments, thecross-member 111 may be omitted in its entirety and each of theprotruding stubs 132 may be attached directly to upper portion 110A ofthe leg brace 110—e.g., each of the protruding stubs 132 attacheddirectly to a respective end portion of the tubular member of the upperportion 110A of the leg brace 110. Omission or truncation of thecross-member 111 beneficially reduces weight of the wheelbarrow 100 andincreases leg room between the support legs for a user of thewheelbarrow 100.

Referring now to FIGS. 6 and 7 , the aforementioned wheelbarrow 100 isdiscussed in the context of a kit 200 (FIG. 6 ) from which thewheelbarrow 100 may be assembled and kit components 201 (FIG. 7 )thereof.
